When to disconnect jumper cables from a car?
Let it sit idle for a few minutes. Start the dead car and run the RPM to about 3000. Let it sit idle for a few minutes. Once you have the dead car up and running, disconnect the jumper cables in the following manner: Positive terminal on the donor car’s battery If your car still doesn’t run, the problem may not be with your battery after all.
What should I do if my car JumpStart does not match?
If they do not match, serious damage can occur to both vehicles. Park the cars close enough for the cables to reach, but they should not touch. Turn the engine off in the car with the good battery. Unplug any accessories (like cell phone chargers); the power surge generated by the jumpstart can short them out.
Can a jumper cable be connected to a dead battery?
Connect the other end of the black (negative) jumper cable to a metal part of the dead car that is unpainted, as far from the battery as the cable will reach. This will ground the circuit and help prevent sparking. Connecting it to the dead battery carries a risk of the battery exploding.
What’s the best way to use a jumper cable?
Turn on emergency lights on both cars if safe. Straighten the jumper cables so there is no room for knots or ties in the either cable. Also, make sure the clamps do not come in contact with each other as this could cause a short circuit.

What happens if you connect the jumper cable backwards?
Car owners may accidentally connect the jumper cables in reverse order or install the battery backward, which causes the vehicle to no longer start. The purpose of this troubleshooting guide is to help answer the following questions: Hooked battery up backward now car won’t start.
What should I do when I hook up a jumper cable?
You should hear the engine shut down and can test the radio to see that it doesn’t have any power running to it. Also take the key out of the car with the dead battery so it can’t start up when the jumper cables are attached. Doing this protects both engines from power surges and reduces the risk of electrical shock.
